Supporting wheel as a rotary support part, the earliest has been widely applied in theminin J cement and other industries. In recent years, along with the steel wire rope factor\wire and cable factor\optical cable factory and other industries flourished, supportingwheel ushers in the spring. But due to the limitation of material, supporting wheel using lifeis relatively short, which has become the bottleneck of the development of supportingwheel industry. Therefore, this thesis focuses on the newly developed high performancesupporting wheel material which were measured related performance calculation, comparesthe properties of materials and make the best choice of material.Using the twin screw reactive extrusion machine products the four formulations of themechanical test samples, and the compression stress-strain curve of the samples of fourkinds of formulation V bakelite and foreign products was measured. It is found that theelastic modulus of the four formulations is between3500MPa and5000MPa which arehigher than the other two samples, in full compliance with the mechanical performancerequirements of the high performance supporting wheel material.Using the finite element software of ANSYS makes the mechanical analysis of thesupporting wheels which are made by the six kinds of specimen to get the displacementdeformation and plastic deformation energy when the supporting wheel is in loadingprocess. In the course of practical work, the supporting wheel is subjected to repeatedsqueezing and the plastic deformation energy is converted into heat becoming the mainfactor to make the internal temperature increasing. The temperature field distribution isanalyzed with thermodynamic analysis knowledge when the supporting wheel is in loadingprocess, then the inner maximum temperature value and its position are obtained when theheat exchange of the six materials is balance. It is found that the maximum temperature of the material3is110.5, which is the smallest in the six kinds of materials. Themaximum temperature value position of the material3is the most close to the outer surfaceof the supporting wheel. Besides, it is found that the load speed and the maximumtemperature is directly proportional.Based on the analysis and comparison of different materials with the test data of themechanical properties and the data of the maximum temperature and its position, it can befound that the material of formaulation3is the best choice for making the supportingwheel.
